all the coloures of a Rainbow?

[Hugh]

what creates Black

[Antoni]

equal amounts of each of the primary colors (red, yellow, blue) will equal black

[Christopher]

Black is the absence of color. This means that if there was no light at all, it would be black.

[Andy T]

Which way you do it?

On a monitor representing light physics, lack of colour.

On paper representing printer chemistry, full of colour.

[Sybil]

Black is absence of color, so far as the colors in light. When mixing colors in a chemical medium (like making paint) black is all colors together or the extreme dark spectra of a color.
